Answers
Answer:
my answer is incorrect
Step-by-step explanation:
Since the two shapes are similar, you can answer this question with a proportion.
[tex]\frac{12}{200} = \frac{15}{area} \\12area = 200*15\\area = \frac{200*15}{12} = 250[/tex]
Another way you could solve it is to find the percentage growth of the height of the area.
[tex]\frac{15-12}{12} = \frac{3}{12} = 25[/tex] percent growth.
We can multiply the area of A by 1.25 to find the area of B
[tex]200*1.25 = 250[/tex]
edit: I was incorrect, it is not linear.
It would be [tex]200*(1.25)^2[/tex]

12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answers
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

The diagram shows ∆QRS. Which term describes point T?
A. circumcenter
B. Orthocenter
C. Incenter
D. Centroid
Answers
Answer:
Step-by-step explanation:
A
The term which describes the point T in triangle QRS is option A. Circumcenter.
Here, given is a triangle QRS.
It is clear that three lines are drawn and all the three lines intersect at the point T.
Each of the line is perpendicular to each of the sides of the triangle.
And each of the line bisects each of the sides, that is sides are being divided in to half.
So T is the intersecting point of all the perpendicular bisectors of the sides, which is the definition of circumcenter.
Thus, T is the circumcenter of the triangle QRS.

Let's solve your equation step-by-step.
2x+9=8x+21
Step 1: Subtract 8x from both sides.
2x+9−8x=8x+21−8x
−6x+9=21
Step 2: Subtract 9 from both sides.
−6x+9−9=21−9
−6x=12
Step 3: Divide both sides by -6.
-6x/-6=12/-6
x=-2
Answer:
-2 = x
Step-by-step explanation:
First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.

HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.
Answers
Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour

This equation shows how the length of Rob's essay depends on the number of hours he spends writing this week. p = h + 11 The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Rob have to spend writing this week in order to have written a total of 16 pages?
Answers
Answer:
Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.
Step-by-step explanation:
From the information given, you can use the formula p=h+11 and solve for h. Then, you have to replace p with 16 to get the amount of hours that Rob will have to spend writing this week in order to have written a total of 16 pages:
p=h+11
h=p-11
h=16-11
h=5
According to this, the answer is that Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.
